    "abstract": "Eigenvectors of decaying quantum systems are studied at exceptional points of\nthe Hamiltonian. Special attention is paid to the properties of the system\nunder time reversal symmetry breaking. At the exceptional point the chiral\ncharacter of the system -- found for time reversal symmetry -- generically\npersists. It is, however, no longer circular but rather elliptic.",
